Words on Repeat is an AI-powered platform designed to help users learn vocabulary from a wide range of content using spaced repetition. The tool enables the creation of study-ready vocabulary decks by pasting a URL, uploading a PDF, importing YouTube subtitles, or entering text directly. Its AI extracts vocabulary, provides translations, example sentences, grammar notes, and grammar cards, and generates flashcards in seconds, eliminating the need for manual card creation.
The platform supports learning in any language pair and offers over 185 curated decks across 12 languages, covering all CEFR proficiency levels from A1 to C2. Users can also browse public decks, create their own for various languages or topics, and organize words into multiple decks, each with its own review schedule and daily study goals. Words on Repeat includes three study modes—standard flashcards, reverse mode (recall the word from its translation), and recall mode (type the answer from memory)—all powered by the FSRS spaced repetition algorithm, which adapts to the user's memory to optimize review timing.
In addition to flashcards, the tool features eight quiz games such as match, write, multiple choice, race, sentence builder, fill-in-the-blank, listening, and crossword, along with printable tests for offline practice. Users can import vocabulary from Anki or export their decks in Anki format (available on paid plans), and save words from any webpage using a Chrome extension. The platform is accessible on any device, including phone, tablet, or desktop, and can be installed as a web app without requiring an app store. Data can be exported at any time, and settings such as dark mode and push notifications for daily study reminders are available.
Words on Repeat offers a free plan that includes unlimited decks, unlimited words, spaced repetition, limited AI extractions per month, quiz games, daily goals, push notifications, and deck sharing. Pro and Pro Max plans provide additional features such as more AI extractions, YouTube import, Anki support, and full analytics. No credit card is required for the free plan.
